Detailed description of the invention
The embodiment of the present invention as shown in Figures 1 to 3, the cross-laminated high-polymer self-adhesion waterproof coiled material of this response type, it is characterized in that comprising basic unit and composite bed 3, basic unit is made up of modified pitch 2, is provided with tire base 1 in basic unit, and tire base 1 is scrim, as chemical fibre fabric, natural plants fabric or composite fibre etc., composite bed 3 is made up of the HDPE film of two-layer above crosswise lamination, and the present embodiment selects 3 layers, and adjacent HDPE film is inclination 45 degree of crosswise laminations.The manufacturing process of the cross-laminated high-polymer self-adhesion waterproof coiled material of this response type is as follows, and each component calculates by mass parts:
A, prepare modified pitch, pitch is placed in retort, heats to 140 DEG C-150 DEG C dehydrations, add random polypropylene and SBS, be mixed evenly, temperature is controlled at 180 ± 5 DEG C, stir 1-1.5h, obtained modified pitch; Each component ratio is pitch 100 parts, random polypropylene 2-5 part, 4-8 part SBS;
B, in retort, add antioxidant, filler, function additive, tackifier, stir 0.5-1h, carry out fully mixed and modified; Each component ratio is: modified pitch 45-55 part that step a is obtained, antioxidant 0.5-1 part, filler 35-45 part, function additive 0.2-0.3 part, tackifier 2-5 part;
C, to be ground obtaining material in b step by colloid mill, then dip-coating on tire base, control thick sizing, cover composite bed, rolling after cooling, basic unit is covered with separation layer prevent from rolling up after bonding.
Wherein said tackifier are asphalt powder or butylbenzene pitch or terpene resin; Modifier is random polypropylene and SBS; Antioxidant is antioxidant TNP trisnonyl phenyl phosphite; Function additive is alkyl alcohol polyoxyethylene ester condensates; Filler is dicalcium powder, talcum powder or flake asbestos.
SBS SBS in modifier is the class modified asphalt material that cost is lower, application is wider, SBS SBS modified pitch, there is excellent hot strength, skin-friction coefficient is large, cryogenic property is good, the characteristics such as good processability; Random polypropylene APP belongs to plastomer modified agent, and can form unique linear network structure in asphalt, can significantly improve the resistance to elevated temperatures of modified pitch, simultaneously to cryogenic property, tensile strength, extension property also has good modification performance.The application of antioxidant antioxidant TNP and functional aid alkyl alcohol polyoxyethylene ester condensates, can realize modified pitch and concrete generation chemical reaction.The primary condition that can mutually bond securely between two kinds of different materials is: surface both performance is identical or close, can be affine mutually.But the different materials used in the application process of cold bonding waterproof material, pitch is the organic matter of the faint polarity of a kind of only tool, water resistant oleophylic; Various concrete or cement mortar are all then the inorganic matters with moisture with natural affinity, the strong polar surfaces of tool, so be incompatible mutually between the two, certainly can not mutually bond securely.Alkyl alcohol polyoxyethylene ester condensates is a kind of surfactant based on nonionic.The terminal polar group simultaneously had in their molecules and nonpolar end group, have extremely strong adhesion with the molecule of concrete and pitch respectively.Due to the existence of alkyl alcohol polyoxyethylene ester condensates, a molecule bridge connected each other has just been erected between pitch and concrete two interface, by it make two kinds of mutual incompatible storerooms can mutually affine, closely adhere to, thus define function and the effect of anti-strip.The modified pitch and the concrete surface that with the addition of alkyl alcohol polyoxyethylene ester condensates form physical absorption and rely on its special chemical constitution to make itself and concrete carry out combination reaction, form powerful chemical tie between them, thus improve modified pitch and concrete adhesiveness, make it have good resistance to heat aging and water resistance, extend the service life of waterproof roll.
Waterproof roll of the present invention and cement or concrete reaction and bonding mechanism: between concrete and modified pitch, adhering size derives from modified pitch in the absorption of concrete surface, infiltration and capillarity; Modified pitch is then that mechanical adhesion is larger in the degree of sprawling of concrete surface to the opposing of water stability, is not subject to water mitigation; Modified pitch represents at degree of the sprawling available contact angle of concrete surface and spreading coefficient, alkyl alcohol polyoxyethylene ester condensates can make the water stability of modified pitch improve, because alkyl alcohol polyoxyethylene ester condensates is a kind of surfactant, it can make modified pitch diminish at the contact angle of concrete surface, and modified pitch improves in the degree of sprawling of concrete surface; The operation principle of alkyl alcohol polyoxyethylene ester condensates is carried out in the process bonded at modified asphalt waterproof coiled material and concrete base layer, the hydrophilic polar of concrete surface is converted into neutrality, before and after reaction, as shown in Figure 2,3, modified pitch and concrete generation chemical reaction form cross-linked structure and produce bonding concrete surface character.When installation of membrane is behind concrete surface, the hydrated calcium silicate (C-S-H gel) that concrete generates in hydration reaction process and calcium hydroxide, chemical equation is as follows:
3CaO·SiO2+nH2O＝xCaO·SiO2·yH2O+(3-x)Ca(OH)2
Si-OH group is there is in concrete, containing TMOS in the lower surface glue-line that waterproof roll contacts with concrete, it and concrete joint react after touch, generate the hydroxyl with reactivity, hydroxyl in this activity hydroxy and Si-OH group reacts, generate ehter bond, gel of calcium silicate and coiled material top layer are formed together with chemical bond and secure attachment.This cementation is very firm, and the environment for use factor by coiled material affects less, and thus it can be bonded on basal plane enduringly, and forms full bonding structure with basal plane.
Composite bed adopts the density polyethylene film with high of crosswise lamination as facing material, and this material adopts the oblique 45 degree of superposition intersections of density polyethylene film with high to make, and have higher tearing strength and dimensional stability, water resistance is more better than general thin.
The present invention can be used for the waterproofing work of the hidden environment such as basement, need to implement to cover on composite bed when the waterproofing work of the exposed environment such as roofing to add metallic aluminium layers of foil, polyester film is covered outside aluminium foil layer, this facing material has higher tearing strength and dimensional stability, protection against the tide, oxygen barrier, shading, shielding, antistatic, water resistance is more better than general thin, solve simultaneously aluminium foil self tearing strength little, very easily tear, oxidizable problem, improve service life of aluminium foil.
